Evaluation method of cooperative jamming effect on radar net based on detection probability

For the scene of cooperative penetration formation against radar net, an evaluation model of jamming effectiveness is established by taking the detection probability of the netted radar fusion center as an evaluation index. Firstly, four effective factors such as time, space, frequency and processing are described in order to calculate the detection probability of single radar when it is under the circumstance of multi-pattern jamming. Then the influencing degree of the detection performance is extended to the radar net in combination with the Rank "K" principle of the fusion center. Lastly, for the scene of the cooperative penetration formation counter against radar net, the weighted integral probability of the detection center for detecting formation is brought forward as a target function of jamming effectiveness, on the basis of taking the air route of the flight formations into consideration. The simulation result shows that the proposed method is practical and effective for evaluating the jamming effect, and is also valuable for improving the overall interference effect of the jammers formation in the electronic counter measure environment.
